1967 Map of Sevenmile Creek

About this map

The Umatilla Indian Reservation Boundary defines the northern and eastern portions of this landscape, reflecting the complex historical geography of Umatilla County. A primary Treaty Boundary line runs through the northern reaches near McKay Creek, where the terrain is carved by deep canyons including McDonald Canyon and Limene Canyon. This territory is marked by significant cultural markers such as the Old Indian Trail, which traverses the high ridges. The hydrological network is centered on Sevenmile Creek, which flows through the heart of the map, supported by numerous named springs like Sevenmile Spring. To the south, the drainages of East Birch Creek and Pearson Creek dominate the topography below Rocky Ridge. While primarily a natural landscape of gulches and flats like Rankin Flats, signs of resource use appear at the Gravel Pit near the southern boundary.
